How easy is it to Decompile .NET apps?

All .NET applications and libraries are compiled to Microsoft Intermediate Language (MSIL). MSIL maintains high-level information about your code including its structure and class, field, method, property and parameter names. With a free decompiler, it is very easy to recreate the source code. Obfuscation and related techniques can make it much more difficult for a hacker or competitor to reverse-engineer your application.

Why use a .NET Obfuscator?

By making a .NET application much more difficult to reverse-engineer, you can help protect against intellectual property (trade secret) theft, bypassing licensing or other access checks, and searching for vulnerabilities.

How does Obfuscation and Code Protection Work?

Various different techniques that complement each other are used to create a layered defense to make reverse engineering, tampering, debugging much more difficult. Some examples include:

Code Before and After Rename Obfuscation and String Encryption Only

.NET Code Before Obfuscation

.NET Code After Baseline Obfuscation

Why should you protect your .NET code against debugging?

Whether a hacker is trying to steal your data, pirate your app, or modify the behavior of a critical piece of software as part of a larger crime – a production debugger is the hacker’s weapon of choice. You should not make it easy for them.

Why do you need to protect your Xamarin apps against rooted devices?

Rooted devices are an important security concern for Android apps. Users root their devices to change to the way the OS operates which in turn allows apps to break out of their normal security safeguards. Running on a rooted device can expose your apps to various dangers such as password stealing keyloggers and malware.
